How to transport an Oscar and His Tank?

Put your filter media in a bag full of tank water. Drain your tank and pack it up.

As long as that filter media stays wet, your beneficial bacteria will live.

As for Mr. Oscar, I would go ask my local fish store for a bag. Bag him up right before you leave, use your bubbler to put some oxygen in the bag, tie it, and get movin!

I recently made a ten hour move with a 55 gallon tankful of fish using that method. I only lost one, and it was because his spines ripped the bag. Oscar will be fine.

Go down to Lowes or Walmart and get some 5 gallon buckets. Use one for the fish and another one or two for some of the water. Don't fill them too full as the lids tend to be not all that watertight. The tank is small enough you can just leave the gravel in there with enough water to cover it while you move it. As for the filter I'd rinse out the media and put it in a bag or something to keep it wet during the trip. Make sure to bring some water conditioner and whatever other supplies you'll need with you to set it back up also.

transport as much of the tank water as you can

take the filter materials dirty and in tank water, do not clean or let it dry out.

get the filter and the dirty materials running on the tank, as soon as you can when you get home

the fish and some water and decorations can go in a cooler, large tupperware/rubbermaid container, new trashcans or buckets.

if you are careful you can siphon out the cleanest water from the tank and only throw away a couple gallons at most when you rinse out the gravel.

2 hours isn't very long, but sometimes I use battery powered airpumps for the fish..and I watch the temperature in the vehicle if it's extreme weather..
